Specification of Letters Patent.

Patented Nov. 5, 1912.

Application filed May 7, 1910. Serial No. 559,983.

To all whom it may concern."-

Be it known that I, FREDERICK SiiIR'rLIrr, a subject of the King ofGreat Britain and Ireland, and residingat Park Road, Hampton Hill, inthecounty of Middlesex, England, have invented a certain new and usefulImprovement in Bailing-Presses, of which the following is aspecification.

This invention relates to presses for pressing bales of jute, cotton,wool, hay, hides, cloth and other materials and of the type wherein afollower or platen is carried on the ends of two links which are pivotedto uprights or levers which in turn are pivoted at their lower ends, thelevers being forced toward each other by suitable means applied at theirupper ends in such a manner that adequate purchase is obtained to thrustdown the follower or platen with the required pressure toward a.stationary table.

The objects of the present invention are to produce a compact andeflicient baling press of this type which shall require the minimum ofhead-room and side room, to provide means for preventing over pressurebeing applied to the bale being pressed due to the negligence orcarelessness of the operator and to devise simple and convenient meansfor placing the box containing the materials to be baled in position inthe press.

In the accompanying drawings, Figure 1 I is an elevation showing acomplete press.

Figs. 2 and 3 are two views illustrating a detail.

In carrying out the invention according j to one mode a pair of uprightsa are pivoted at or near their lower ends I) to a frame 0 composed ofmetal joists, although it is to be understood that wooden members may beused if desired. A stationary table or lash- 1 ing plate 03 on which thematerials to be baled are placed rests upon the girders e mounted on theframe 0. Pivoted at f to the upper ends of the levers a are the linkswhich are connected at their lower ends to a platen or follower h bymeans of pivot pins 70 in brackets-Z and the ends of the links adjacentto the platen are provided with gears or toothed segments m in order toinsure that the links shall work in unison and that the platen h shallbe moved parallel to the lashing-plate (Z. F or similar reasons toothedsegments n are secured to the lower ends of the l vers a, and thesesegments are so arranged that they will gear with one another for anydegree of travel of the press. The upper.

curved in the form of an arc struck with the center of the pivot pin fas center, and fastened to the end of the lever s is a cable or rope tcarrying at its lower end a counterweight M adapted to cause the platenh to move upward when the winch is released, said counterweight beingarranged to slide in a groove in the lever on or between twosimilar-halves of the said lever. The cords or cables I? are caused toremain tangential to the levers s by means of pulleys or sheavespivotedto the levers a. The curved levers 8 may be replaced by straight leversif they are hinged where they join the links 9.

It is to be understood that the winch used for forcing the leverstogether may be of any suitable form and may be driven by hand or by anysuitable form of power. The preferred form of winch is clearly shown tothe left in Fig. 1 in which the drum 1" is of the spiral groove type,tapered from one end to the other, and mounted on a shaft 10 carried ina frame 00. Mounted upon the shaft w is a spur wheel 1 adapted to gearwith a second smaller pinion 2 mounted upon a shaft 3 which carries atits other end a spur wheel 4. The spur wheel 4 is adapted to mesh with aspur wheel 5 carried on the shaft 6, which also carries a fast and loosepulley 7 and 8, arranged to be operated from any convenient source ofpower by means of the belt 9. One convenient form of apparatus forautomatically stopping the winch when the desired pressure has beenapplied to the bale and the latter is down to size, is illustrated.Mounted on a shaft 10 attached to the frame of the winch is an arm orlever 11, while the shaft 10 also carries a bent arm or lever 12 adaptedto engage with a lever 13loosely mounted upon the shaft 10 and carryingat its end a weight 14:. A sector 15 having a link attached to it bymeans of pins in such a way that thelever 13 is free to move between thesector 15 and the link but to be arrested in its movement by the pins isalso loosely mountedupon the shaft 10. The

sector 15 is provided with a slot 18 with which engages a pin secured toor formed integral with the arm 20 which passes through guides in thewinch frame and carries at one end the belt guide 21. The other end ofthe arm 20 is arranged to rest when the winch is in motion, on a lever22 pivoted to a short shaft 23 and carrying at one end a counterweight24. Also rigidly mounted on the shaft 23 is a link or lever to which issecured one end of a brake band 26, the other end of which is fixed, andwhich is adapted to surround the spur wheel 1.

The action of the apparatus is as follows :When the bale is beingcompressed in the machine the rope p is traveling from the large to thesmall end of the winch drum r. As soon as the rope reaches the lever 11it causes the latter to tilt, thus also rotating the lever 12, which inturn pushes over the lever 13 carrying the counterweight 14. As soon asthis counterweight is pushed beyond the vertical it falls by its ownweight, and the lever 13 striking the pin causes the sector 15 torotate, thus, through the medium of the slot and the pln pushing the arm20 along, and causing the belt to move from the fast pulley 7 to theloose pulley 8. At the same time, as soon as the arm 20 is moved off thelever 22, the weight 24 falls and causes the shaft 23, with the link torotate thus tightening up the brake band 26, and causing the winch tostop. By suitably arranging the lever 11 to be adjusted in differentpositions, the winch may be caused to stop as soon as the bale is downtoany required size.

Figs. 2 and 3 illustrate a device for enabling boxes containing heavymaterials to be simply and rapidly placed in position in the press. Thelashing plate and materials are placed in a box 27 (Fig. 1) open at thetop and provided with doors in the front and side.

In the following description the apparatus at one side only of the boxwill be described, but it is to be understood that a similar apparatuswill be attached to the other side of the box, the whole box beingadapted to run on wheels 28 in turn guided on rails 29 (Fig. 1).Attached to the side of the box is an angled piece 30 extending thewhole length of the box, and to which are secured two pins 31 on each ofwhich are pivoted levers 32 and 33 carrying a plate or bar 34- kept inits normal or raised position by means of the counterweight 35 attachedto one of the levers 33. The height of the bar 34 in its upper positionis so arranged that it is above the level of the girders 6 (Fig. 1)which in turn are slightly above the level of the angle pieces 30. The

lashing plate (Z is placed on the bars 34: in the box 27 which is thenfilled with the material to be baled and pushed along the rails 29 intoposition in the press. Just before the box is in its correct position,the

counterweight 35 strikes against a projec tion 40 on each side (Fig. 1)with the result that the counterweights immediately push the leverssupporting the bars 34 out of the vertical, the weight of the materialsin the box thereupon depressing the bars 3-1 into the position indicatedby chain dotted lines in Fig. 2. The lashing plate and materials in thebox are thus deposited in position on the girders e, the weight beingtaken off the frame of the box 27, which can then be wheeled away fromunder the press if desired.

Then it is desired to disconnect the gearing of the winch this may beeffected by means of a hand-lever 39 pivoted at one end and carrying apin 38 which is adapted to engage with a groove 37 to a clutch 36mounted on the shaft 3.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1.
